Enzalutamide is a medication primarily used to treat advanced prostate cancer. It works by blocking the effects of androgens, such as testosterone, which can promote the growth of cancer cells. By inhibiting these hormones, Enzalutamide helps slow down the progression of the disease and can improve survival rates in patients. This drug is typically prescribed for men whose cancer has spread or is resistant to other treatments. Enzalutamide is taken orally, usually in the form of a capsule, and is often part of a broader treatment plan that may include other therapies or medications to manage prostate cancer effectively.
